First off, I have searched this issue 8 ways from Sunday, so I heartily apologize if I missed a thread that already discussed it. I know how annoying it can be to see the same stuff asked over and over! 
Okay, my two current problems:
1. I would like a shortcut on one of my home screens that goes directly to the Directions section of Maps:
Is that possible?
2. Using voice to instigate a nav session (via car home, voice search, whatever) I literally cannot make it create a route to my home address by saying "Navigate to Home." I have done the following:

Am I asking Maps to do things it can't yet do, or am I just a clueless newb?

- Nicknamed my wife as "Home" with our address filled out in contacts
- Created a new contact named "Home" with our address
- Created a map on Google Maps called "Home" and starred it
